Body Shop are doing 3 for 2 on make up but again its the most expensive item you get free. I bought eyelash curlers and tea tree concealer and got the £16 shimmer cubes free - all for £7.60. Its free delivery using code FREEDEL plus use the code DHAD000058 to get 20% off get even more discount. Or BODYSHOP5 for £5 off £25 spend. You can mix and match the make up to whatever you use - just make sure you get a really expensive item as it will be FREE. Order over £25 and get free body scrub worth £12.50 as well (thanks poohbeanie). Hope this makes sense! Keep checking out of stock stuff as it comes back into stock quite quick usually. FREEDEL for free delivery.
There's a few things for £4 or so like tea tree oil but think they're selling quickly. You can get emailed when they're back in stock though as their stock comes in and out quite a lot for some reason.
